Question

Find the exact value. tan 75 degrees

Answer 1

Do you have a scientific calculator? :)

Answer 2

not with me sadly

Answer 3

calculi tan(45+30)=?

Answer 4

than you dont know it you can rewrite it like

sin(45+30)
---------- = ?
cos(45+30)

Answer 5

\[\tan 75=\tan \left( 45+30 \right)=\frac{ 1+\tan 30 }{ 1-\tan 30 }=?\]

Answer 6

@jhonyy9 I still don't understand and do not have a calculator with me to solve this problem.

Answer 7

tan 30 = sin30/cos30 = 1/2/sqrt3/2 = 1/2 *2/sqrt3 = 1/sqrt3 = sqrt3 /3

so now just substitute in this formula what have wrote to you surjithayer above - ok ?
